摘要:

对银杏极短枝叶片叶绿素、花青苷和黄酮含量进行全周期测定,结果表明:黄酮含量分别于1999-07-04和1999-11-01达到高峰,其中后1次峰值较大、持续时间较长;叶绿素含量于1999-06-13达到最高峰后一直呈下降趋势;花青苷含量变化趋势与黄酮类似,但波动幅度较黄酮大。用Microsoft Excel软件对数据统计分析,黄酮与花青苷显著正相关,与叶绿素显著负相关。回归方程为:Y(叶黄酮) =220.9558- 0.7722X1(叶绿素) +0.4343X2 (花青苷) ,回归模型经F测验达1%显著水平。从生理生化角度对调控黄酮含量进行了讨论。

Abstract:

The concentrations of chlorophyll, anthocyanin and flavonoid in Ginkgo biloba leaf were assayed in 1999. The results indicate that there are two peaks of flavonoid content, one on July 4 and the other that has greater value on Nov.1. Chlorophyll shows a declining trend after reaching its peak value on June 13. Anthocyanin shares a similar trend with flavonoid, but its curve fluctuates larger than that of flavonoid. With the help of Microsoft Excel to deal with data, there is a significantly positive relationship between flavonoid and anthocyanin, a significantly negative relationship between flavonoid and chlorophyll.The regression equation,Y(flavonoid)=220.9558-0.7722X1(chlorophyll)+0.4343X2(anthocyanin), is statistically significant at the 1% level. How to regulate the flavonoid concentration on the physiological and biochemical viewpoints is discussed.
